It's Powerball mania time again across the country, when daydream multimillionaires begin budgeting for gold-plated yachts, diamond-crusted toilet seats and steak and lobster lunches.

The current Powerball jackpot stands at $400 million, the sixth-largest in U.S. lottery history. Last Saturday's $330.8 million jackpot had no winners. Tonight’s jackpot is the result of 15 drawings going without a jackpot winner.

The Powerball jackpot’s cash value is $227.8 million, according to the Texas Lottery.

Charlie Patel with Paradise Gifts in the downtown tunnel says he's seen brisk sales since the jackpot climbed to $400 million, with a steady stream of customers coming by to try their luck. If his store sells the winning ticket he has big plans.

"We would give some to our employees and to charities," Patel said.

The winning numbers will be picked at 9:59 p.m. Central time. Texas ticket sales cut off at 9 p.m., so you have until that time to purchase a ticket.

Powerball ticket sales in Texas began in early 2010, and over 11 million winning tickets have been sold in the state since, according to the Texas Lottery.

Texas finally had its first Powerball jackpot winner just last year, when a man from Ravenna won $40 million on a Quick Pick ticket. The convenience store that sold it to him snagged a $400,000 retailer bonus just for selling the winning ticket.

The game, played in 43 states plus Washington, D.C., and the U.S. Virgin Islands, has seen a surge in its jackpot figures since the ticket prices rose from $1 to $2. According to Powerball's online FAQ, which is one of the funniest FAQ sections on the Internet, about 70 to 80 percent of Powerball winners comes from computer-generated numbers.

Sadly, the feds will want to take a bite out of your winnings right off the bat. The maximum federal income tax rate for 2013 was 39.6 percent.

According to lottery calculator site USA Mega, if you were to take the lump sum option from a $400 million prize, you will walk away with $227.8 million minus $56.95 million going to the federal government, leaving you with $170.85 million.
